Small collision systems: Theory overview on cold nuclear matter effects

Small collision systems: Theory overview on cold nuclear matter effects

Many observables measured at the Relativistic Heavy Ion Collider and the Large Hadron Collider show a smooth transition between proton-proton and protonnucleus collisions (small systems), and nucleus-nucleus collisions (large systems), when represented versus some variable like the multiplicity in t...
